Petersburg National Battlefield has acquired color infrared aerial photographs of the park. This project will produce a digital orthorectified mosaic from the photography. Detailed vegetation polygons will be classified using The Nature Conservancy's National Vegetation Classification System. Typically zoom transfer scopes are used to develop this type of vegetation database. However, we are scanning and rectifying the aerial photography scanned at 600 dpi and rectified in ERDAS IMAGINE using DEMs and DOQQs. The vegetation polygons are then created directly on the computer screen in ArcView GIS 3.1.
